8. Net Loss per Share

Basic loss per share is computed based on the net loss allocable to common stockholders for each period, divided by the weighted average number of common shares outstanding. All outstanding stock options and restricted stock units are excluded from the calculation since they are anti-dilutive. Due to the existence of net losses for the year ended December 31, 2017, 2016 and 2015, basic and diluted loss per share were the same.
